Why is bower not working - "bash: bower: command not found"?

Question

bash

Help me figure it out, I'm working in the bush through ConEmu , I installed git, nodejs, npm, bower globally and locally, an entry appeared in the package.json file in the project
{
"devDependencies": {
"bower": "^1.8.0"
}
}
I checked the versions - everything is installed. I'm trying to install jquery and normalize.css:
bower install --save jquery#1.8 normalize.css,
the message is: bash: bower: command not found, I've tried different commands: bower -v, bower list etc, always gives - bash: bower : command not found.
Tell me how to fix?
